City Public Service Prepares for Competition Through Automation

The Forces of Change: Technology and Deregulation

The utility industry is undergoing a dramatic restructuring driven largely by deregulation and shifts in the economy. Rapid change looms on the horizon, especially for the electric utility industry. While it is always difficult to predict the future with certainty, history gives us useful guidelines about what is likely to happen as restructuring moves forward.

Software and the Changing Utilities Market

When Newmarket Hydro goes on line this summer with new software to serve its 20,000 customers more efficiently, it will simultaneously replace an obsolete information system and improve its cash position by about $600,000. What the commission is doing is consistent with an emerging trend among utilities to be more competitive with hydro rates and generally improve services to customers. Otherwise there is a very real risk of being privatized or absorbed into a regional public utility.

“Geo-engineering” System Empowers Hawaii Department of Water Supply

Almost two-thirds of the State of Hawaii`s land area is on the "Big Island" of Hawaii. On those 4,038 square miles lie white sandy beaches, tropical rain forests, rolling pasture lands and the majestic Mauna Kea and Mauna Loa. Also on the island are some 35,000 water customers who consume 7.4 million gallons daily. They are served by 27 water systems managed by the Department of Water Supply (DWS), County of Hawaii.

Electric Utilities Continue to Make Strong Investments in Automation

Electric utilities in the United States and Canada are planning 333 SCADA system projects over the next two years. The projects are valued at more than $315 million. And, 64 projects have budgets exceeding $1 million. These projects and others are described in a series of detailed reports published by PennWell Research.

Meter-reading Communication

The Telereader TR101 by Nertec is repackaged to fit inside single-phase meters. Installed on existing meters in minutes, the TR101 reports readings in various intervals from increments of 15 minutes to seven days and reports power outages. The module is totally remote and communicates via the telephone, thus enabling the transfer of meter reading information and reprogrammed instructions. The TR101 retrofits any existing single-phase meters.
